I am building an attached green house to my garage. It will have a cement slab with drains a covered roof and windows on three sides. I live in the mountains outside of Denver and have been having a hard time finding information to get going? I am interested in finding out about grow lights, exhaust fans, watering system and humidification for an area 9 1/2 feet by 11 1/2 feet. My plan is to grow herbs, tomatoes, and vegetables year round. Any information on lights, fans, watering system and humidification would be greatly appreciated for this beginner.
